The Institute of Energy and Nuclear Research (IPEN) is the research unit of the MCTI responsible for the production and distribution of radioisotopes originating in nuclear reactors and the radiopharmaceuticals that use these radioisotopes for use in nuclear medicine. The production of IPEN meets an annual demand of about 2 million nuclear medicine procedures in 430 Brazilian hospitals and clinics. Consider a 115 mCi radioactive tracer produced at IPEN. Fifteen hours later, when he is delivered to a hospital, his activity is 95 mCi. The lowest usable activity level is 10 mCi. The half-life of the tracer and the time it will remain usable after arriving at the hospital are, respectively: a) 58 h and 177 h b) 58 h and 204 h c) 54.4 h and 177 h d) 58 h and 188 h e) 54,4 horas e 192h
